Problems solved by technology
Restricted by the height of the thin coal seam working face, the overall height of the coal mining equipment such as the shearer, hydraulic support, and scraper conveyor is required to be relatively low. The surface and the lower surface make the height of the middle groove higher, resulting in a higher height of the scraper conveyor, which cannot meet the height requirements of the thin coal seam for coal mining equipment

The invention discloses a scraper conveyor of a continuous coal mining system for mining thin coal layer, comprising a central slot (1) and an electric cable slot (2) fixedly connected with the central slot (1), wherein the electric cable slot (2) is installed at the outer side wall of the central slot (1). Thus, the electric cable slot is arranged at the side wall of the middle slot; the electric cable slot does not occupy the space of the middle slot in the height direction so as to reduce the height of the middle slot and further reduce the height of the scraper conveyor; and the scraper conveyor is more applicable to the thin coal layer mining. The invention further discloses a continuous coal mining system comprising the scraper conveyor.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a scraper conveyor used in a continuous coal mining system for thin coal seam mining. The present invention also relates to a continuous coal mining system comprising the above-mentioned scraper conveyor. Background technique [0002] my country is the main coal-producing country in the world, and the total number of coal mines exceeds the sum of the number of coal mines in all other countries in the world. With the rapid development of my country's economic construction, the coal industry is constantly developing towards mechanization and automation, and comprehensive mechanized coal mining equipment is becoming more and more It is more widely used in coal production under various geological conditions. [0003] In the operation of mechanized coal mining, scraper conveyor, as a working face conveying equipment, is one of the core equipment of mechanized coal mining in c...
